中文摘要: 将混凝土坝中广泛应用的冷却水管技术引入到船闸结构的温控中。通过在边底板中埋设金属冷却水管与未采用相应措施的边底板及中底板进行对比，分析冷却水管对闸首底板的温控效果。结果表明，冷却水管可显著改善底板混凝土内部的温度分布，对降低内外温差和温度应力起到较为明显的效果。 英文摘要: This paper introduces the cooling water pipe techniques widely used in concrete dams to the temperature controlling methods of lock structures.The study intends to find the temperature cooling effect of cooling water pipes,by laying metal cooling water pipes in one side bottom-board of lock head and making a contrast with corresponding middle bottom-board and side bottom-board which have no such measures.The result proves that cooling water pipes can improve the distribution of temperature field noticeably,and also achieve good results in cutting down the temperature difference in the construction of concrete and decrease the thermal stress very well.
